I don’t know where you getting this from, but Rojava is generally considered the most democratic faction in Syria. They’re not marxists, they instead follow democratic confederalism (a form of libertarian socialism). As per Wikipedia:
While entertaining some foreign relations, the region is neither officially recognized as autonomous by the government of Syria, state, or other governments institutions except for the Catalan Parliament.[19][20][21] The AANES has widespread support for its universal democratic, sustainable, autonomous, pluralist, equal, and feminist policies in dialogues with other parties and organizations.[22][23][24][25] Northeastern Syria is polyethnic and home to sizeable ethnic Arab, Kurdish, and Assyrian populations, with smaller communities of ethnic Turkmen, Armenians, Circassians, and Yazidis.[26][27][28]
I’d say they’re the best chance Syria and the Kurds have at liberation.
Good one
